Section 1 - Description & Operation

1-1 THE OIL SHEAR PRINCIPLEConventional brakes and clutches depend on friction be-tween solid surfaces operating in air to transmit torque. Friction can do the job, but produces a great amount of heat and wear, causing an increase in replacement parts, maintenance, and downtime.

In Force Control Oil Shear Drive Systems the friction surfaces operate in cooling and lubricating fluid. The oil molecules tend to cling to each other as well as the friction surfaces. As moving and stationary elements are brought together, a thin but positive film of oil is main-tained between the friction surfaces, controlled by the clamping pressure and carefully designed grooves in the friction material.

Torque is transmitted from one surface to the other through the viscous shear of the oil film. The friction surfaces are protected by this film and therefore sur-face wear is greatly reduced. The positive flow of fluid between the discs also effectively transmits heat away from the friction surfaces.

1-2 DESCRIPTIONThe Size 210 Shaft Mounted Posistop Brake is a multiple surface, spring activated, pneumatic release braking de-vice that effectively dissipates the heat generated from frequent starting and stopping.

This 210 Posistop Brake has a range of 20 Lb. Ft. to 90 Lb. Ft. of braking torque. This in accomplished with 5 different Brake Stack Configurations, which are de-scribed in Section 2.

The brake is mounted and locked to a driven or jack shaft by a Locking Collar that effectively locks the brake hub to the driven shaft. The torque arm in mounted to the back face of the brake.

Finned Aluminum Housing for maximum heat dis-sipation.
